SAMUEL IEELLEGRINO, OF MONESSEN, PENNSYLVANIA.

PADLOCK.

To all whom it may concern:

Be it known that I, SAMUEL PELLEGRINO,

residing at Monessen in the county of VVestmoreland and State ofPennsylvania, have invented certain new and useful Improvements inPadlocks, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to pad locks and has for its object to provide alock of such class, in a manner as hereinafter set forth, with a springpressed locking member engaging in the shackle for maintaining thelatter closed and to further provide a lock with means to permit ofsufliciently shifting said spring pressed locking member to release theshackle when the occasion so requires.

With the foregoing and other objects 111 view the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views :Figure 1 is a longitudinal sectionalview of a pad lock in accordance with this invention. Fig. 2 is an endview. Fig. 3 is aside elevation. Figs. 4 to 9 are details.

Referring to the drawings in detail 1 denotes a cylindrical lock casinghaving its inner face formed with a pair of lengthwise extending grooves2 which are arranged opposite each other. The casing 1 is closed at oneend through the medium of a head 3, the latter having abuttingthereagainst a retaining member 4, provided with a centrally disposedopening 5 having a stepped wall which provides a shoulder 6 and whichforms the opening 5 of two different diameters. The retaining member 4has a lateral lug 7 which engages in the opening 8 formed in the casing1 for the purpose of maintaining said member 4 in position against saidmember 3. The member 4 is notched as at 9, and said notch 9 registerswith an opening 10 formed in the body of the casing 1 at one endthereof. The head 3 is notched as at 11, and the inner wall of saidnotch 11 Specification of Letters Patent.

is beveled, and the said beveled inner wall flush with the beveled innerwall 12 of the a citizen of the United States of Amerlca,

notch 9. The casing 1, opposite the end provided with the opening 10,has an opening 13.

Arranged longitudinally of the casing 1, is a rotatable spindle 14,having a head 15, which is arranged in that portion of the opening 5 ofgreater diameter and is prevented fromlongitudinal shifting by theshoulder 6. The spindle 14 intermediate its ends has peripheral threads16, and said spindle 14 is of a length to project from that end of thecasing 1 provided with an opening 13. The retaining member 4 constitutesa bearing for one end of the spindle 14.

The reference character 1? denotes a disk and the said disk 17 has apair of lugs 18 which are seated in the edge of that end of the casing 1which is provided with the opening 13. The lugs 18 prevent shifting ofthe disk 17 The reference character 19 denotes a shackle, and the armsof the latter are indicated at 20, 21. The free terminus of the arm 20is reduced as at 22, extends down through the opening 10, and into thenotch 9, and is pivotally connected to the member 4 by a pin 23. Thebeveled wall of the notch 11 and the beveled wall 12 of the notch 9provides a clearance for the reduced terminus 22 of the arm 20 when thelatter is swung in one direction on its pivot. The free terminus of thearm 21 is reduced as at 24 and it extends down through the opening13.The reduced terminus 24 has a groove 25.

Arranged within the casing 1, is a longitudinally extending shiftablesliding support 26, the latter has an enlarged opening 27 for thepassage of the spindle 14 and said member 26 is formed on one face witha pair of lugs 28, having mounted there be tween a nut 29. The latterpermanently engages with the threads 16 of the spindle l4 and isprevented from rotation by the lugs 28. The lugs 28 are formed on oneface of the member 26, and the latter has proi jecting from its otherface an arm30.

Rotatably mounted upon the spindle 14 is a locking member 31, formedwith an anelongated nular flange 32, the latter being notched as at 33to provide clearances. The flange 32 is adapted to engage in the groove25 of the arm 21 of the shackle 19 for the purpose of locking the same.WVhen the member 31 is shifted into the notch 33 the arm 21 of theshackle 19 can be swung from out the cas ing 1.

Formed integral with the locking member 31 and projecting forwardlytherefrom is a sleeve 33, which provides a bearing for the outer end ofthe spindle 1 1 and said sleeve 33 finds a bearing in the disk 17.Formed integral with the outer end of the sleeve 33 and arrangedexteriorly of the easing 1 is a disk 36 which is employed forretainingthe locking member 31. The spindle 14L projects forwardly fromthe disk 36 and has fixed thereto a disk 37 for the purpose of turningsaid spindle. The locking member 31 has a seat 38 for the free end ofthe arm 30.

Surrounding the spindle 1 1 and interposed between the member 1 and thenut 29, to prevent looseness of the latter, is a coil spring 39 andsurrounding the spindle 14 and interposed between the disk 36 and thelocking member 31 is a coil spring 40. The function of the spring 10 isto maintain the locking member 31 in the groove 25 of the arm 21 of theshackle.

It will be assumed that the parts are in theposition shown in Fig. 1.The spindle 14: is rotated in one direction so that, the nut 29 willmove toward the member, 1 thereby releasing the tension of the spring40. The disk 36 is then revolved which carries a locking member 31therewith until the notch 33 is opposite the groove 25, which willprovide a clearance for the inner terminus ofthe arm 21 of the shackleand said arm can be swung clear of the casing 1.

The locking member 31 is prevented from rotation by the arm 30 whichengages in the seat 38. hen the support 26 is shifted toward the memberby the expansion of the spring 4-0, the arm 30 is' moved out of thenotch 38 in the member 31.
